在中国医学科学院病毒研究所的实验室里,有一台美观大方、加工精细的“CCPD临界点干燥仪”,这台仪器能使生物标本在表面张力为零的情况下完全干燥,保持了生物标本的原生状态,为科研人员探索微观世界的奥秘创造了条件。这台仪器是我省平阳县科学仪器厂在中国医学科学院病毒研究所、中国科学院上海昆虫研究所等单位帮助下,克服了技术力量薄弱,设备简陋等困难试制成功的。最近通过技术鉴定,获得省内外有关专家、科研人员的一致好评。临界点干燥仪是扫描电镜生物标本制作的必须设备。当生物标本在空气中干燥时,因失去水分及表面张力的牵引,使细胞表层
In the laboratory of the Institute of Virology, Chinese Academy of Medical Sciences, there is a beautiful and sophisticated “CCPD critical point dryer,” which allows the biological specimen to be completely dried at a zero surface tension with the biological specimen The original state, for researchers to explore the mysteries of the micro-world created the conditions. This instrument is our province Pingyang County Scientific Instrument Factory in the Chinese Academy of Medical Sciences Institute of Virology, Chinese Academy of Sciences, Shanghai Institute of Entomology and other units with the help of overcoming the technical strength of the poor, crude and other difficulties of successful trial. Recently, through technical appraisal, access to relevant experts from home and abroad, researchers alike. Critical point dryer is the SEM equipment necessary for the production of biological specimens. When the biological specimen is dry in the air, due to the loss of moisture and surface tension traction, so that the cell surface
